Ben Flower punched an opponent, who was defenceless on the ground, in the Super League Grand Final— a move that was a major factor in his team’s title chances and an act that will now be remembered as one of the worst and disturbing images in the sport of rugby.

Flower, via a statement from his team, Wigan has since apologised for the unacceptable act.

“I am so sorry for what happened last night.There is no defence for my actions. It is something that happened in the heat of the moment. I instantly regretted it and am devastated that I allowed myself to punch someone like this,” Flower said.

“At Wigan … we may aim to dominate teams, but we don’t aim to hurt people. I firstly offer my apologies to Lance. I hope he is OK. I’d also like to say sorry to my team-mates, our fans and the Wigan club. I accept I’ll have to live with this for the rest of my career. Finally, I’m sorry to the sport of rugby league. It was a big night and I know I’ve taken attention away from a special event.”

No official statement has been issued by the league yet and no word on possible long-term sanctions on the Wigan prop.

Flower has been dismantled by league fans on social media Twitter since the incident with many having a few choice words for the 26-year-old player:

Ben Flower's behaviour last night has no place in sport. Absolute disgrace #throwthebookathim

Ben Flower's attack has ended up on the back of the sun nicknaming the sport thugby. Well done Flower... Great advert — London Faithful (@LondonFaithful) October 12, 2014

Watching the Grand Final re-run. Can't believe Ben Flower isn't facing criminal charges. The first punch happens in RL, the second doesn't.

Just seen Ben Flower's punches on Lance Hohaia in the rugby. Never witnessed anything like it. Crazy. — Leigh Curtis (@LeighCurtis_NP) October 12, 2014

What Ben Flower did was wrong! To punch someone when they are already knocked out is just pathetic!

Wigan chairman Ian Lenagan and Wigan coach Shaun Wade also issued a statement apologising for Fowler’s actions:

“We apologise unreservedly, on behalf of the Wigan club, to Lance Hohaia, St Helens and the general rugby league family for Ben Flower’s totally inappropriate behaviour in last night’s Grand Final,” the pair said.

Does Ben Flower merit additional penalty for the punch? Should the fans continue to call for his head? Will the league levy a harsher penalty in the coming days?
